PUMP.

'TLPIECIPICATION forming part of Letters Patent No. 334,936, dated January 26, 1886.

Serial No. 173,341. (No model.)

To all whom it may concern.-

Be it known that I, JOHN W. COLLIER, of Lockport, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Pumps; and I do hereby declare that the following description of my said invention, taken in connection with the accompanying sheet of drawings, forms afull, clear, and exact specification, whiclrwill enable others skilled in the art to which itappertains to make and use the same.

My present invention has general reference to pumps; and it consists, essentially, in the novel and peculiar combination of parts and details of construction, as hereinafter first fully set forth and described, and then pointed out in the claims.

In the drawings already mentioned, which l serve to illustrate my said invention more fully, Figure l is a front, and Fig. 2 a side, elevation of my improved pump. Fig. 3 is a longitudinal sectional elevation of a portion of the pump, showing the construction of the nozzle and vent. Fig. 4. is a transverse sectional elevation on line 2 z of Fig. 3. Fig. 5 is a longitudinal section on line :0 z of Fig. 4. Fig. 6 is a transverse section on line yg of Fig. 3.

Like parts are designated by corresponding letters of reference in all the figures.

The object of my invention is the production of a suction and force pump that shall be capable of throwing a steady and continuous stream of water from the nozzle, as well as from a hose-nozzle; and to attain this very important and desirable result I construct this pump, essentially, of apumpcylinc'ler, A, having the usual foot-valve and piston (not shown) and the ordinary base, I. This cylinder has an upper enlarged portion, A, provided with the spout or nozzle 0, and it is closed by a-cap plate, 0, having the stuffingbox L, for the passage of the piston-rod II.

From the enlarged portion Alead-s a branch, D, carrying the air-chamber E, having exteriorly the fork 0, within which is pivoted the handle F, connecting with the piston-rod H by a link-connection, G, as clearly illustrated in the drawings.

In the interior of the enlarged portion or chamber A there is a vertical passage, a, having an outlet, or, near the cover or cap- I plate 0, and terminating with its other end in piston rises, and there being usually no out let from this chamber, except the nozzle, compression of the air in said chamber takes place. This causes a forcible ejection of the water discharged from said nozzle when the hose is not attached, and therefore an inter rupted stream of varying force and velocity. This objectionable feature, however, is removed from my pump by the introduction of the auxiliary dischargepassage a a c, which allows the air to escape as soon as the water rises in the chamber,- thus filling the said chamber quickly, while, when the piston moves down fora new stroke, air can enter the chamber through the said passages, to allow the complete discharge to take place rapidly and evenly. As soon as the hose-coupling and hose are applied, the portion i, Fig. 5, covering the outlet of the passage 0, prevents the escape and influx of air from or into the said chamber A. In this case the said chamber acts, in conjunction with the airchamber E, as an auxiliary air-chamber, and assists in throwing a continuous stream from the hose-nozzle. The passages a and c are shown located within the chamber A, respectively,of the nozzle 0. This position is not essential, however, inasmuch as both ma be placed outside of the said chamber and nozzle without changing the action of the parts, as long as the discharge-opening a is within the said chamber.

Having thus fully described my invention, I claim as new and desire to secure to me by Letters Patent of the United States- 1. A hand-pump consisting, essentially, of the pump-cylinder A, having base B and upper enlarged chamber, A, provided with a branch, D, the air-chamber E, handle F, and a suit-able piston and piston-rod connected with said handle, said chamber A having a vertical passage commencing at the upper end of said chamber and terminating outside of the same in or near the discharge-nozzle C, substantially as and for the object stated.

2. The combination. with the cylinder A, having the enlarged chamber A, closed by a cap, 0, of the nozzle 0, having the hosecoupling J K, said chamber being provided with an auxiliary outlet, a a c, terminating in the face of the said nozzle, substantially as and for the purpose specified.-

3: In hand and other pumps, a nozzle for the discharge, having a double passage, one being the regular and main discharge and the other an auxiliary one terminating in the uppermost portion of the discharge-chamber, whereby the discharge from the said cham her is through both passages at the beginning of the stroke, and through the main passage only during the return of the same, and whereby said auxiliary passage serves as a 20 vent for the said chamber, to facilitate the discharge through said main passage, substantially as and for the object stated.

4. The nozzle 0, having a main passage, 0, and auxiliary passage 0, in combination with 25 a hose-coupling, I, having the closing portion 71 for said auxiliary passage, as and for the purpose specified.

In testimony that I claim the foregoing as my invention I have hereunto set my hand in 0 the presence of two subscribing witnesses.

JOHN W. COLLIER.
